`To all 'whom t may concern: l

`1Be it known.` that I, GEORGE lVIiaBAw, of Jersey City,vin the countyof Hudson, State of `N ew Jersey, have invent-ed a new and originalcombination-namely a Tenn plet `or Tool for Cutting Miters; and I dohereby declare that the'following is a full,

clear, and exact description thereof, reference being liadto theaccompanying draw ings and letters of reference marked thereon.

In Figure I, A, is the stock or bed-piece of the tool or machines thatis, the piece to which the other parts are attached; andinA reference towhich they act.

It is made of wood, iron or other suitable material. undersurface ismade with themost caution as it is the main plane of referenceand use incutting by theymachine `or tool.` B, B, are guides or stops, that holdor guide'tlie holding of the templet or miter,` while it is being used.Y The guides B, B,may be` fixed ofusing the templet or miter;-thatis,said

and stationary `as represented in the drawings, or they may be so madeas to adjust y the chiseled edge to an angle more or less than a rightangle; or `may be otherwise varied in their position to give greaterfacility right angle meaning the placing the line of the edge ofthechisel at right angles to ,the longitudinal axis of the material to becut. C, is the segment, or portion of a circle;

` made of metal or `other suitable material and marked with degreesvarying from nothing to ninety or ,more degrees; or it may be withoutmarks, the operator using y the templet, making his own marks or o-theriwise` determining the angle at which lie `wishes `the chisel to cut. Theobject of O- the 'segment-is to set the pitch or angle of the chisel..In `the drawings it is represent-` ed` (Fig. 1,) as having a slot C, a,:0, and a set screw D, in said slot so that the frame i of the chiselmay be fixed.

E, holding the chisel `may be `placed and fastened by the set screw, D,at any point in the slot; and thus the direction and angle The center of3 the segment, and the pointof the angle by which the frame E, and thechisel G, is fixed, is at C, a, E, is the frame that holds and guidesthe chisel G. It is made of any strong and "durable material. J, J, aregrooved or slotted guides at the lower` eX- tremity ofthe frame, andhold the chisel in theframe. The points C, a, and C, a, a, are thehinges on which the frame turns. The frame incloses the chisel on `threesides and has a round holeatfK, which receives the handle ofthe chisel,said hole withthe .chisel handle further fguiding thel chisel, whilecutting. H, is aspring on the chisel handle to retract the chisel, and.the force ofthe spring is regulated by the set screw I, .p

which `moves ont the thread cut on the handle. F, is a knob to receivethe blowof or force to the Ichisel.` As equivalents `I dethe chisel orothermode of applying powery scribe any wood,iiron,fbrass or other framef1.,

whetherinadewvith the exact slotted guides st-antially the same; or `anyapparatus of J, J or not, and whether there be a hole at i fK in theframe or not.v Any frame sub-` mechanical means` producing the same end.i

As to angle, I describe as equivalents a chisel xed at any one anglewithout the segment C and the setscrew D. That is that `virtually makesa tool or machine cutting a miter of any arc; or of more than one angle.So lof the slot C, a, as', and the handle;

and the knob; while I describe them, I de` so knowing and expressing thefact, that, some or. all. may be varied, and some may be omittedaltogether. At K, in the `frame E, is a circular hole through which apor!I tion of the chisel handle slides, when the f chisel cuts. Theunited action of the guide pieces J, J and the frame for the chisel, E,

and thesliding of the rounded handle of the chisel through the hole atK, is to cause the chisel to move on a plane; and said `plane is oneside `of an angle between two planes meeting at t-he center CML; whilethe other side of the angle is the medium plane of the bed piece orstock described.

`In Fig. II, A, is. an anterior view of the chisel, represented `as outof its frame and separated from the stock,` and B, is a lateral I Viewof the same, showing that the chisel is 2 represented as a` thin firmer.I now 'furth'er describe a mortising chisel or any other chisel as` anequivalent thereunto. I-I, is a spring on the chisel handle seen at Aand B,

Fig. II. Also the knob is seen, to receive theblow of the mallet, or ofthe hand or other source of power, that moves the chisel` The elementsof the machine or tool are the stockV to hold the templet or miter inits place on the materialto be cut the stop guides, that `help to holdthe tool or machine on the material; the segment to regulate anddetermine the angle or bevel 'cut by the chisel; the chisel to cut thematerial;

the spring handleto operate the chisel; and

i the frame to guide the chisel. Any one or all; any' portion necessarytoproduce the desired result of cutting miters or bevels by an integralhand tool or machine.

The operationA of the templet, bevel or mitering tool or machine, is asfollows. I

n take the material to be cut, for example,

1 L a miter boX. Then if the panel of the door is square, that is hasright angles at its corners, I set the. chisel by the segment C and theset screw D; holding the frame E, andthe chisel, &c., at an angle of l5degrees.A Then placngthe stop guides lagainst the molding, I apply powertothe knob F, and thus cut or pare smoothly, and nicely the miter orvbevel, or angle required; producing an accurate and complete fitting ofthe molding to the panel of the door. So of any other angle or any otherkind of Work.

Thus With necessary modiiications, I apply the tool or machine to allthe Work it is capable of executing; and thereby secure beauty offinish; as Well as saving of time in the operation.

The combination and arrangement in the manner described; or in anymanner equivalent thereunto, o the several specific parts; or theirequivalents, of the hereinbefore described miter machine; Withoutlimiting myself to any particular arrangement of parts, for the purposeset lforth. c
